An Empirical Demodulation for Electrical Fault Detection in Induction Motors

IEEE Transactions on Instrumentation and Measurement, 2016
Signal demodulation is a fundamental procedure in many situations during a spectral analysis. Through an envelope analysis, it becomes possible to identify fault frequencies that are embedded in a modulated signal and that are not clearly visible only by directly applying some signal processing techniques such as the Fourier transform and filtering. In

Fault Detection of Actuator Faults for Electric Vehicle

2007 IEEE International Conference on Control Applications, 2007
The main purposes of this paper concern: fault generation of nonlinear analytical redundancy for actuator faults of electric vehicle. These relations are used to detect and isolate actuator fault based on the elimination of the unknown variables of the system. Each residual, obtained by elimination theory, is sensitive to only one actuator fault thanks

Contactless Electric Fence Fault Detection System

2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2019
Electric fence fault finding can be tedious and time consuming, something that farmers often do not have. This can have a direct impact on the farmer’s lifestyle as the fence may become physically damaged, stock may escape, and time will be spent fixing these problems.

Data-Driven Fault Detection of Electrical Machine

2018 15th International Conference on Control, Automation, Robotics and Vision (ICARCV), 2018
For the purpose of monitoring the health conditions of electrical machines, a framework is proposed to establish the methods to provide an early warning to potential machine failures in data mining terminology. The framework consists of five stages including data segmentation, feature extraction/selection, multi-classifier ensemble, decision fusion and

MODEL EQUATION AND FAULT DETECTION OF ELECTRIC MOTORS

IFAC Proceedings Volumes, 1991
Abstract The paper describes one possibility of detection faults in d.c. motors with parameter estimation in the frequency domain. The result gives the type of fault and its location. The models which are needed for the parameter estimation were developed and improved by measurings on low power d.c. motors. The remaining model errors are in the order

Fault Detection and Diagnosis in Spacecraft Electrical Power Systems

Journal of Aerospace Information Systems, 2023
The ability to accurately identify and isolate failures in the electrical power system (EPS) is critical to ensure the reliability of spacecraft. This paper proposes a novel solution to the problem of fault detection and diagnosis in direct current (DC) electric power systems for spacecraft.

Electrical monitoring for fault detection in an EMA

IEEE Aerospace and Electronic Systems Magazine, 2010
The concept of a "More Electric Aircraft" (MEA) leads, among other actions, to the substitution of hydraulic-based actuators for Electro-Mechanical Actuators (EMA). Removal of the engine hydraulic pumps requires fully-operative electrical power actuators and mastery of the flight control architecture.

Fault Detection and Automated Fault Diagnosis for Embedded Integrated Electrical Passives

Journal of VLSI signal processing systems for signal, image and video technology, 1999
In this paper, we propose a novel test technique for fault detection and automated fault diagnosis using pole/zero analysis of embedded integrated passive. For pole/zero analysis, an ensemble of circuits obtained by perturbing the circuit under test parameters using their known statistical distributions is generated.
